Rolex Cookie Monster vs Blueberry sounds simple at first. Both names point to blue Rolex watches, and both appear often in listings, dealer pages, and watch forums. That is where many readers start to get confused. On the surface, they can seem more similar than they are.
Each name stays remembered for a different reason. A newer blue Rolex gives one model a stronger modern look. The other remains relevant because of Rolex’s history and the long-running collector discussion. They share the same color, but they do not carry the same story.
This guide helps you separate the nickname from the actual watch. You will see what each name refers to, why people mix them up, and what matters once you look closer. If you want a clear and useful comparison before reading further, this guide will help.
Rolex Cookie Monster Overview
Rolex introduced the Submariner Ref. 126619LB in 2020 as part of the wider Submariner update. It replaced the Smurf (Ref. 116619LB), which collectors knew for its full blue look. This newer version kept the blue bezel but changed the dial to black. Soon after release, collectors started using Cookie Monster for the new model.
That change gave the watch a different identity within the Submariner line. Rolex likely made this version to keep the white gold Submariner distinct from the earlier model while giving it a sharper, more contemporary look. Case size also moved from 40mm to 41mm, in line with the rest of the updated range.
Collectors usually remember this watch for its white gold case, blue bezel, and black dial. It has the same basic shape as a Submariner, but white gold makes it much heavier than a steel model, so the added weight is noticeable as soon as you put it on.
Its most recognizable feature is clear. This is the only modern Submariner with a blue ceramic bezel, black dial, and white gold case. That setup gives it a look no other current Submariner shares.

Rolex Blueberry Overview
Rolex made the GMT Master Ref. 1675 from 1959 to 1980. Rolex built it for pilots who needed to track two time zones during flights. Most examples came with a red and blue bezel or a black bezel. Collectors later used Blueberry for rare 1675 watches fitted with an all-blue bezel.
That bezel is what sets this version apart. Rolex did not offer it as a normal catalog model, which is why it became a long-running point of debate. Most research suggests these inserts appeared in small numbers through special orders, service replacements, or other limited channels. So the watch itself was familiar, but the bezel made it unusual.
Collectors usually focus on the blue bezel and its uncertain background. Some accept it as a genuine period Rolex variant with a limited history. Others stay more careful because Rolex never treated it as a standard retail version. Even so, it remains one of the most recognized unusual 1675 setups.
The Blueberry is known for its full blue aluminum bezel on the vintage GMT Master 1675. That single detail gives it a very different look from the usual Pepsi or black bezel versions. Once you know it, the watch is easy to pick out.

Cookie Monster vs. Blueberry: Most Notable Differences
Cookie Monster and Blueberry may share a blue theme, but they come from very different parts of the Rolex lineup. One was built as a modern dive watch, while the other started as a vintage travel watch with a different job on the wrist.
Below are the main differences that matter once you look past the color.
1. Watch Complication
The Cookie Monster is a dive watch. Its bezel turns in one direction and tracks elapsed time for up to 60 minutes. That matters underwater because the bezel cannot move forward by mistake and show more remaining time than you really have. With 300 meters of water resistance, it is built for real diving, not only surface use.
The Blueberry is a travel watch. Its bezel turns both ways and works with the GMT hand to read a second time zone on a 24-hour scale. This setup lets you track local time and home time simultaneously. Water resistance is only 50 meters, so it’s suitable for daily wear, light rain, and occasional water exposure, not diving.
2. Bezel Material
On the Cookie Monster, Rolex uses a blue Cerachrom ceramic bezel. Ceramic is harder than aluminum, resists scratches better, and holds its color longer. The platinum-filled numerals also keep the scale clear over time.
With the Blueberry, the watch uses a blue aluminum bezel insert. Aluminum marks and fades more easily, especially on an older watch. That matters more here because the bezel is the main feature that gives the Blueberry its identity.
3. Case Design
Rolex makes the Cookie Monster’s case and bracelet from 18k white gold. It keeps the familiar Submariner shape, but it feels much heavier than a steel model. That extra weight is more noticeable the moment you put it on.
For the Blueberry, Rolex used a stainless steel case. Steel keeps the watch lighter and closer to the original purpose of the GMT Master tool watch. It does not have the dense feel of white gold, but it is easier to wear for long periods.
4. Movement Generation
Inside the Cookie Monster is Caliber 3235, Rolex’s modern automatic movement for the Submariner Date. It offers a 70-hour power reserve, quick-set date, and newer Rolex parts such as the Chronergy escapement and Parachrom hairspring. Daily use is more convenient because the watch runs longer and resets faster.
Most Blueberry examples use Caliber 1575, while earlier 1675 models used Caliber 1565. Both movements run the main time, date, and GMT hand for a second time zone. The difference is mainly in the production period, not the added function, so daily use feels largely the same.
5. Crystal Type
On the Cookie Monster, Rolex fits a sapphire crystal with a Cyclops magnifier. Sapphire is much more scratch-resistant than acrylic, so it stays cleaner in daily wear. Along with the glossy dial and modern lume, visibility stays sharp and clear.
On the Blueberry, Rolex used an acrylic crystal. Acrylic scratches more easily, but light marks can often be polished out. At the same time, it gives the watch a softer look, which suits the vintage GMT Master style.
Price and Market Demand
The Cookie Monster trades like a modern-day Rolex in precious metals. Current production, white gold pricing, and a smaller buyer pool than steel sports models shape its market. Retail is about $48,774, while the market price is near $34,181 (source). Most examples sell for around $34,500 to $35,500, with stronger full-set pieces reaching about $37,900.
The Blueberry trades like a vintage Rolex, where condition and setup drive value. Buyers look harder at the bezel, dial, and overall originality, so prices spread out more. Original retail was about $5,039, while the current market sits near $16,398 (source). Entry examples can start around $8,088, while stronger high-end pieces can reach about $46,436.
Taken together, the Cookie Monster trades below retail because it starts from a high modern price and faces a smaller buyer pool. The Blueberry trades above retail because its old retail price no longer drives the market.
